Description
1. Solid-core pure calcium wire: constructed by rolling and crimping a steel strip around the outer layer, with a calcium wire core enclosed within.
Ingredients | Ca % | All | Magnesium | Mn | Yes | Fe | Calcium wire weight (g/m) | Strip thickness (mm) | Wire diameter (mm) |
less than or equal to | |||||||||
Content | 97±1 | 0.8 | 0.7 | 0.5 | 0.5 | 0.5 | 47-75 | 0.4-1.0 | 9.5±0.5 |
2. Double-layer solid pure calcium wire: composed of a calcium wire encased by an inner steel strip and then rolled and crimped along the edge by an outer steel strip; the thickened steel strips enable the calcium wire to be inserted deeper into the molten steel.

3. Solid calcium-aluminum wire: composed of a calcium wire core encased in an inner aluminum sheath, with the outer steel strip rolled and crimped to form a secure bond.

4. Solid-core calcium-silicon wire: This product is manufactured by wrapping an outer steel strip around an inner core of calcium wire and ferrosilicon powder, with the edges crimped and interlocked during rolling. It replaces traditional calcium-silicon powder-cored wire, reducing the introduction of impurities, achieving higher and more stable recovery rates, and significantly lowering calcium treatment costs.
